Lens assembly structure for frameless glasses {ASSEMBLY STRUCTURE OF LENS FOR RIMLESS GLASSES}

The present invention relates to a lens assembly structure for rimless glasses, and more particularly, to a lens assembly structure for rimless glasses, which can improve the bonding force between the rimless glasses lens and the leg of the glasses, and prevent the lenses from being worn or damaged. It is about.

In general, the glasses are divided into a so-called frameless glasses configured to be used to fix the spectacle lens without the spectacle frame is formed to fit the lens.

The rimless glasses can be manufactured very lightly because there is no glasses frame rim (RIM) that fixes the lens, and it forms a hole in the lens and connects the lens, the end piece and the temple (TEMPLE). It is configured to.

Since the rimless glasses do not have a rim to fix the lens, it is difficult to fix the lens and the fixing force is weak, so that the joint portion of the lens and the end piece is easily broken or deformed. .

5 is a view illustrating a lens coupling structure of the rimless glasses disclosed in Korean Utility Model Model No. 400236. The lens 51 has a coupling hole 50 formed therein, and an end piece formed to penetrate the coupling hole 50. A bolt 53 coupled to the 52, a nut 54 coupled to the bolt 53 to fix the lens 51, and a bolt 53 and a nut formed on the bolt 53. 54 is a head portion 55 for applying elasticity when coupling the lens 51 to improve the fixing force of the lens 51.

That is, in order to fix the lens 51 in the frameless glasses, the coupling hole 50 is formed in the lens 51, and then the nut 54 is coupled to the bolt 53 penetrating the lens 51. By pressing, the lens 51 is fixed.

However, as described above, when the coupling hole is formed in the lens to fix the lens in the rimless glasses, and the bolt installed in the end piece is inserted therein and the nut is coupled to the lens, the lens is supported by the head. Substantially the bolt and the lens is in direct contact, which causes a problem that the lens is easily worn or broken.

That is, the head of the bolt supports the lens, but there is a play between the lens and the bolt and nut, which causes the lens to flow, so that the lens (engagement hole) is worn out by the tightening of the bolt and nut, which is metal, or the head is pressed. It is broken by.

Accordingly, an object of the present invention is to solve the above problems, and to improve the bonding force of the lens in the frameless glasses to prevent the flow of the lens and to prevent wear and breakage of the lens by bolts and nuts. It is to provide a lens assembly structure for frameless glasses.

In order to achieve the above object, the present invention, in the lens assembly structure for a rimless glasses including a lens formed with a coupling hole in the coupling position of the end piece,

The end nut is fixed to the end piece and is formed to be inserted into the coupling hole, and the lens and the end piece are engaged with the coupling hole of the lens while expanding when the screw is inserted into the fixing nut and screwed with the fixing nut. And a securing means configured to secure.

As described above, the present invention expands when the fixing nut and the fixing bolt are combined to further improve the bonding force with the lens, thereby preventing the flow of the lens and preventing the lens from being worn or damaged. In addition to safe use, there is an advantage to improve the life of the frameless glasses.

1 is an exploded perspective view showing a lens assembly structure for a rimless glasses according to the present invention, Figures 2 and 3 are enlarged cross-sectional view showing a coupling state of the fixing bolt and the fixing nut, the end piece 52 and the bridge (B) One end is fixed to the lens 51 formed with a coupling hole 50 at the coupling position of the lens 51 and coupling means such as welding to the end piece 52 and / or the bridge B and inserted into the coupling hole 50. The fixed nut 1 and the fixed nut 1 are inserted into the fixing nut 1 and screwed, and when the screw is engaged with the fixing nut 1, the fixed nut 1 is engaged with the coupling hole 50 of the lens 51 to engage the lens 51. And fastening means configured to fix the end piece 52 and / or the bridge B.

That is, in order to couple the lens 51, the end piece 52, and the bridge (B), when the fixing bolt 2 and the fixing nut 1 are combined, the fixing means expands and fixes the lens 51. By maximizing the coupling force of the nut 1, the fixing force of the lens 51 can be improved more.

The fixing means includes a first taper (3) formed on a part of the fixing bolt (2), and the first taper (3) when the fixing bolt (2) is inserted into the fixing nut (1) and screwed together. The second taper 4 formed on the inner surface of the fixing nut 1 and the forming portion of the second taper 4 to be extended by the fixing bolt 2 so as to extend outward by It consists of the extension part 6 in which many 5 is formed.

Particularly, in the fixing nut 1, a ring-shaped coupling protrusion 7 is formed on the outer surface of the extension part 6, and the coupling hole of the lens 51 when the extension part 6 is expanded. (50) The bonding force with the inner side surface can be further improved.

That is, since the force of the fixing nut 1 and the coupling protrusion 7 extends substantially perpendicular to the coupling hole 50, the coupling force with the coupling hole 50 is maximized and the coupling hole 50 is There is no play between the, so that it is possible to prevent wear and breakage generated between the lens 51 and the fixing nut (1).

Referring to the operation and effect of the present invention as described above, in order to combine the lens 51, first the fixing nut 1 fixed to the bridge (B) is inserted into one coupling hole 50 of the lens 51 And the fixing bolt (2) is inserted here.

When the fixing bolt 2 is inserted into the fixing nut 1 and screwed together, the first taper 3 of the fixing bolt 2 comes into close contact with the second taper 4 of the inner side of the fixing nut 1, If the fixing bolt (2) continues to rotate is in close contact with the coupling hole 50 of the lens 51 is expanded (6).

That is, as the fixing bolt 2 is tightened, the expansion part 6 expands and comes into close contact with the inner surface of the coupling hole 50 of the lens 51. Therefore, the lens 51 and the fixing nut 1 and the bridge B are separated. Cohesion can be maintained firmly.

Of course, the force between the fixing bolt 2 and the fixing nut 1 and the coupling hole 50 of the lens 51 is applied to each other so that the fixing bolt 2 is not easily released by external vibration or the like. do.

When the bridge B is coupled to the lens 51, the end piece 52 is coupled to the lens 51 again. The fixing nut 1 fixed to the end piece 52 is coupled to the coupling hole 50. Inserting and coupling the fixing bolt (2) to it is easy to combine the lens 51 and the end piece (52).

As described above, when the lens 51, the end piece 52, and the bridge (B) are combined by the fixing nut 1 and the fixing bolt 2 which are tightly fixed to the lens 51 while expanding when combined, The clearance between the 51 and the fixing nut 1 does not occur, and as a result, the flow of the lens 51 does not occur, thereby improving the bonding force of the lens 51 and preventing wear and damage. will be.
